6.2.1 BOILER CONFIGURATION

The  REC10  UI  is  supplied  with  a  default  configuration  that 

enables a standard type of external control, e.g. room 

thermostat & clock, programmable room thermostat, etc. to 

be connected to the appliance or alternatively the Vokera 

BeSMART OT+ control. Alternatively and if desired the 

embedded 7-day clock can be enabled (default is disabled) to 

control the ON/OFF time schedule for the central heating. In 

order to enable the embedded clock, it is necessary to access 

the ‘INSTALLATION’ parameters as defined in section 8 (see 

also menu hierarchy on page 18).

NOTE

Do not enable the embedded clock if another type of timing 

control, e.g. time clock, programmable room thermostat, etc. 

is – or will be – connected to the appliance, in order to manage 

the heating timing schedule.

The following functions can also be accessed and adjusted via 

the installer parameters (see section 8 & page 18) if required/

necessary.

NOTE

The ‘installer’ parameters should only be accessed and 

adjusted by suitably qualified personnel.

  This parameter allows you to change the TIMER OFF 

CH, regarding the delay time introduced for re-igniting the 

burner in the face of an off due to the heating temperature 

being reached. The factory setting for this parameter is 3

DOMESTIC HOT WATER THERMOSTAT

  This parameter allows you to set the type of DOMESTIC

  The factory setting for this parameter is RELATED, i.e. for 

domestic hot water the boiler switches off at se5°C 

and restarts at se4°C.

  To select the ABSOLUTE values, where the boiler for 

domestic hot water will still switch off at 65°C and restart at 

63°C, use the keys 

“up”

 and

PREHEATING

  Setting PREHEATING = 1 the boiler’s domestic hot water 

function activates. This function keeps the water in the 

domestic hot water exchanger hot, to reduce standby times 

when a request is made. When the preheating function is 

enabled the symbol P comes on with a steady light at the 

top with respect to the hot water icon. During burner ignition 

following a preheating request, the symbol P starts flashing.

  To deactivate the preheating function, set the parameter to 

PREHEATING = 0, the symbol P switches off.

  The function is not active when the boiler is OFF.
